Description of key information

From the water surface the substance will not evaporate into the atmosphere. 

Key value for chemical safety assessment

Additional information

The Henry’s law constant was estimated with the Bond method to 4.11 x E-13 Pa x m3/mole (at 25 °C) (BASF AG, 1998), indicating that IBDU is not expected to partition significantly into the atmosphere.
